Apparatus for the treatment of surfaces involving the use of at least a solvent

摘要

An apparatus for the treatment of at least one surface of an article contained therein is disclosed. The treatment apparatus comprises a treatment enclosure which includes at least one inlet lock-chamber and at least one outlet lock-chamber with an article transport device extending therebetween. The treatment enclosure includes a solvent dispenser which is positioned with an outlet thereof adjacent the article transport device. Included within the apparatus is a vapor extractor for extracting air-solvent vapors from the treatment enclosure. The vapors extracted from the treatment enclosure are directed through a condenser positioned between the inlet lock-chamber and the outlet lock-chamber. Recycling ducts, communicating with the treatment enclosure and the vapor extractor, are also provided for recycling air, from which the solvent vapors have been substantially removed, toward the inlet of the inlet lock-chamber and the outlet of the outlet lock-chamber.
